The
Boot Sequence
screen options determine the order in which the system searches hard-
disk drives for the files that it needs to load during system startup. The choices depend on
the particular hard-disk drives installed in your system. You can enable or disable a device by
selecting it and pressing the spacebar. To change the order in which devices are searched,
use the <+> and <-> keys.

The following devices on the system board are configured through this screen:
 SCSI Controller
— determines whether the system's integrated small computer sys-
tem interface (SCSI) controller is enabled. Changes take effect after reboot.
 Network Interface Controller
— determines whether the system's integrated network
interface controller (NIC) is enabled. Changes take effect after reboot.
 NIC MAC Address
— displays the address of the media access control (MAC) address
used by the integrated NIC. This field has no user-selectable settings.
 Mouse Controller
— enables or disables the system's mouse controller. Disabling the
mouse controller allows an expansion card to use IRQ12.
 Serial Port 1, Serial Port 2
— configure the system's integrated serial ports. These
options can be set to
Auto
(the default) to automatically configure a port, to a particular
designation, or to
Off
to disable the port.
If you set a serial port to
Auto
and add an expansion card containing a port configured to
the same designation, the system automatically remaps the integrated port to the next
available port designation that shares the same interrupt request (IRQ) setting
 Parallel Port
— configures the system's integrated parallel port.
 Parallel Port Mode
— controls whether the system's integrated parallel port acts as an
AT-compatible (unidirectional) or PS/2-compatible (bidirectional) port. To determine the
correct mode to use, see the documentation that came with the peripheral device con-
nected to the serial port.
 USB Controller
— enables or disables the system's Universal Serial Bus (USB) ports.
Disabling the USB ports makes system resources available for other devices.
 IDE CD-ROM Interface
— enables or disables the system's IDE CD-ROM interface.
 Diskette Controller
— enables or disables the system's diskette drive controller. With
Auto
(default) selected, the system turns off the controller when necessary to accom-
modate a controller card installed in an expansion slot.
 Speaker
— determines whether the integrated speaker is
On
(the default) or
Off
. A
change to this option takes effect immediately (rebooting the system is not required).
